I think it was from the FloraNova Bloom and Sea Green. They both look like mud and make the water brown. The roots are not slimey and they smell like carrots. I think I just burned them with high nutes and low O2. Now they are just trying to recover. You can actually see some new growth in there so I have a good feeling about this beneficial root slime tea. I am also trying to get the ppm lower. I will do another res change and flush. She really seams to like that. It is when I start adding nutes that she slows down. I might just go straight water, tea, and 0-10-10 after the res flush.
Cheers,
Mo
